Description

Lautsprecher und Mikrofone in Sprechanlagen, welche im Freien angebracht sind, insbesondere die Türlautsprecher, müssen gegen das Eindringen von Insekten geschützt werden.Loudspeakers and microphones in intercoms, which are installed outdoors are, especially the door loudspeakers, must be protected against the entry of insects to be protected.

Die nachstehend beschriebene Ausführung hat gegenüber den bekannten Anordnungen den Vorteil, daß der Spannring, der das Sieb, welches das Eindringen von Insekten verhindert, für die gemeinsame Schallöffnung des Lautsprechers und Mikrofons festklemmt, von einem Haltewinkel abgestützt wird, der gleichzeitig auch mit Aufhängeösen für das Mikrofon versehen ist. In Fig. i ist die Anordnung im Schnitt und in Fig.2 in der Draufsicht gezeichnet.The embodiment described below has compared to the known Arrangements have the advantage that the clamping ring, the sieve, which the penetration prevented from insects for the common sound opening of the speaker and Microphone clamped, is supported by a bracket, which at the same time also is provided with hanging loops for the microphone. In Fig. I the arrangement is in section and drawn in Fig.2 in plan view.

Die Frontplatte i, welche auf einem allseitig geschlossenen Gehäuse aufsitzt, ist entsprechend dem Durchmesser des Lautsprechers 2 durchgedrückt und mit einer jalousieartigen Schallöffnung 3 versehen. Das feinmaschige Sieb .4, welches das Eindringen der Insekten verhindert, wird durch einen Spannring 5 an die Frontplatte angedrückt. Der Spannring wird durch drei Haltewinkel 6, die auf der Frontplatte befestigt sind, abgestützt. Die Haltewinkel sind so ausgebildet, daß sie einerseits den Spannring stützen und andererseits eine ausgedrückte Aufhängeöse 7 haben, an der die Federn 8, an denen das Mikrofon a aufgehängt ist, befestigt werden.The front panel i, which is on a housing that is closed on all sides is seated, is pushed through according to the diameter of the loudspeaker 2 and provided with a louvre-like sound opening 3. The fine-mesh sieve .4, which the penetration of insects is prevented by a clamping ring 5 on the front panel pressed on. The clamping ring is secured by three brackets 6 on the front panel are attached, supported. The bracket are designed so that they on the one hand support the clamping ring and on the other hand have an expressed hanging loop 7 on which the springs 8, on which the microphone a is suspended, are attached.

PATENTANSPRÜCHE: i. Einrichtung für ein koaxial mit einem Lautsprecher angeordnetes Mikrofon, dadurch gekennzeichnet, daß der Spannring für ein die gemeinsame Schallöffnung für den Lautsprecher und das Mikrofon abdeckendes feinmaschiges Sieb, z. B. zum Schutz gegen Insekten bei Türlautsprecheranlagen, von Haltewinkeln abgestützt ist, die auch die Aufhängeösen für das Mikrofon tragen. PATENT CLAIMS: i. Means for a coaxial with a loudspeaker arranged microphone, characterized in that the clamping ring for a common A fine-meshed sieve covering the sound opening for the loudspeaker and the microphone, z. B. to protect against insects in door loudspeaker systems, supported by brackets that also carry the hanging loops for the microphone. 2. Einrichtung nach Anspruch i, dadurch gekennzeichnet, daß die Haltewinkel (6) derart geprägt sind, daß sie sich der Prägung der Frontplatte und dem Querschnitt des Spannringes (S) anpassen und dadurch der Spannring (S) gegen das Sieb (4) gepreßt und dieses festgeklemmt wird. Angezogene Druckschriften: Deutsche Patentschrift Nr. 828 74; USA.-Patentschrift Nr. 2 195 65i.2. Device according to claim i, characterized in that the bracket (6) are embossed in such a way that they adapt to the embossing of the front plate and the cross-section of the clamping ring (S) and thereby the clamping ring (S) is pressed against the sieve (4) and this is clamped will.
